C=2pi(r)
Radius= 1/2(diameter)
Radius = 4km
C= 2(3.14)(4km)
C=25.12km
108, and 110 because the pattern is multiply by 4, then add 2
Factors are the numbers that go into 52 evenly with no remainders.
So the factors of 52 are : 1,2,4,13,26,52
The reflection of the point (x, y) across the y-axis is the point (-x, y). When you reflect a point across the line y = x, the x-coordinate and the y-coordinate change places. Notice how each point of the original figure and its image are the same distance away from the line of reflection (x = –2 in this example).
